    SleepCoach.AI

    Developing a proactive iOS application using SwiftUI and a modular MVVM architecture, designed to ease the cognitive load of new mothers by intelligently managing infant sleep routines. Beyond standard data tracking, I am integrating an on-device AI agent that analyzes historical sleep patterns, wake windows, and daily behaviors. This agent dynamically predicts optimal nap schedules and proactively suggests context-aware routine adjustments directly within the UI, without requiring manual prompts. To support this autonomous feature, I engineered a 3-layer orchestration pipeline (Context Ingestion, Background Reasoning, State Mutation) utilizing dedicated background Actors and Swift Concurrency (async/await). This ensures multi-step LLM reasoning executes seamlessly without blocking the Main Actor. Focused on scalable architecture, thread safety, and preserving structural identity during asynchronous UI updates.
